The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0042] The following describes the ignition coil seal ring pull-out force measurement system and method of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the pull-out force measurement in the related art mentioned in the above background technology cannot completely restore the actual working conditions, and effectively monitor the pull-out force difference before and after the aging of the seal ring rubber, thereby reducing the reliability of the verification parts, the present application provides an ignition coil seal ring pull-out force measurement system, in which a pull-out force measurement component is assembled on the engine cover; a pressure sensing unit assembled on the pull-out force measurement component is used to measure the pressure signal when the ignition coil seal ring falls off; a data acquisition unit is connected to the pressure sensing unit, and is used to convert the pressure signal into pressure data when the ignition coil seal ring falls off, so as to obtain the pull-out force data of the ignition coil seal ring based on the pressure data. Thus, the pull-out force measurement in the related art cannot completely restore the actual working conditions, and effectively monitor the pull-out force difference before and after the aging of the seal ring rubber, thereby reducing the reliability of the verification parts, and the like, by using a new ignition coil and a real engine cover to perform pull-out force measurement, the pull-out force difference before and after the aging of the seal ring rubber is accurately monitored to verify the reliability of the parts.

[0043] Specifically, Figure 1 A block diagram of an ignition coil sealing ring pull-out force measurement system provided in an embodiment of the present application.

[0044] like Figure 1 As shown, the ignition coil sealing ring pull-out force measurement system 10 includes: a pull-out force measurement component 100 , a pressure sensing unit 200 and a data acquisition unit 300 .

[0045] Among them, the pull-out force measuring component 100 is installed on the engine upper cover; the pressure sensing unit 200 is installed in the pull-out force measuring component 100, and is used to measure the pressure signal when the ignition coil sealing ring falls off; the data acquisition unit 300 is connected to the pressure sensing unit 200, and is used to convert the pressure signal into pressure data when the ignition coil sealing ring falls off, so as to obtain the pull-out force data of the ignition coil sealing ring based on the pressure data.

[0046] Optionally, the pull-out force measuring component 100 includes: a pull-out force measuring cylinder, which is connected to the pressure sensing unit 200 and contacts the inner side of the ignition coil sealing ring, and is used to control the pressure signal generated by the pressure sensing unit 200 to meet the uniform distribution condition; a pull-out force measuring disc, which is connected to the pull-out force measuring cylinder and contacts the outer side of the ignition coil sealing ring, and is used to cooperate with the pull-out force measuring cylinder to control the pressure signal generated by the pressure sensing unit 200 to meet the uniform distribution condition; and a pull-out force measuring plate, which is mounted on the engine upper cover and is used to install and fix at least one component to be measured.

[0047] Optionally, the above-mentioned ignition coil sealing ring pull-out force measurement system 10 further includes: an ignition coil sealing ring, the ignition coil sealing ring is connected to the engine upper cover, and is used to control the pressure signal to be in a preset stable state.

[0048] Specifically, in order to solve the risk of the engine ignition coil sealing ring being detached from the upper cover during endurance testing or long-term operation, thereby causing problems such as reduced engine sealing performance, difficulty in starting, insufficient power, increased fuel consumption, etc., the embodiment of the present application uses a brand-new ignition coil sealing ring and a real engine upper cover to measure the pull-out force, restore the actual working conditions and environment, and thus accurately monitor the aging of the ignition coil sealing ring rubber and the difference in pull-out force before and after aging of the ignition coil sealing ring rubber, thereby verifying the reliability of the parts and significantly reducing the failure rate of engine sealing problems.

[0049] Specifically, if Figure 2 As shown, the ignition coil seal ring pull-out force measurement system 10 of the embodiment of the present application mainly includes an engine upper cover 1, a pull-out force measurement assembly 100 and an ignition coil seal ring 8. The pull-out force measurement assembly 100 is mounted on the engine upper cover 1, and the ignition coil seal ring 8 is connected to the engine upper cover 1 to control the pressure signal to be in a preset stable state. Among them, the pull-out force measurement assembly 100 includes a pull-out force measurement plate 2, a pull-out force measurement cylinder 6 and a pull-out force measurement disc 7, a bolt assembly (i.e., a long bolt 3, a long bolt 4 and a short bolt 9) and a pressure sensing unit 200 (i.e., a force sensor 5).

[0050] Furthermore, in an embodiment of the present application, the force sensing unit 200, the pull-off force measuring cylinder 6, the pull-off force measuring disc 7 and the ignition coil sealing ring 8 are assembled from the bottom of the engine upper cover 1 upward, and the pressure sensing unit 200 is assembled in the pull-off force measuring component 100, and a brand model with a suitable range of measurement needs to be selected to measure the pressure signal when the ignition coil sealing ring 8 falls off. The pull-off force measuring cylinder 6 is connected to the pressure sensing unit 200 and contacts the inner side of the ignition coil sealing ring 8 to control the pressure signal generated by the pressure sensing unit 200 to meet the uniform distribution condition. The pull-off force measuring disc 7 is connected to the pull-off force measuring cylinder 6 and contacts the outer side of the ignition coil sealing ring 8 to coordinate with the pull-off force measuring cylinder 6 to control the pressure signal generated by the pressure sensing unit 200 to meet the uniform distribution condition. The pull-off force measuring plate 2 is assembled on the engine upper cover 1 to install and fix other components to be measured of the ignition coil sealing ring pull-off force measurement system 10, and maintain stability and consistency during measurement.

[0051] Optionally, the above-mentioned ignition coil sealing ring pull-out force measurement system 10 further includes: a bolt assembly, which is fixedly assembled with the pull-out force measurement assembly 100 and is used to fix the pull-out force measurement assembly 100 .

[0052] Optionally, the bolt assembly includes: a first bolt assembly, which is assembled on the engine cover and is used to fix the pull-out force measurement plate to be horizontally aligned with the engine cover; and a second bolt assembly, which is vertically assembled at the center position of the pull-out force measurement plate and is used to apply pressure to the pressure sensing unit 200.

[0053] Optionally, the second bolt assembly further includes: an adjustment unit, which is connected to the second bolt assembly and is used to adjust the screw-in depth of the second bolt assembly when the screw-in depth of the second bolt assembly does not meet a preset screw-in condition.

[0054] Among them, the preset screw-in conditions can be set by technical personnel in this field according to actual measurement requirements, or can be obtained through a limited number of computer simulation measurements, and are not specifically limited here.

[0055] Specifically, in the embodiment of the present application, the first bolt assembly (i.e., the long bolt 3 and the long bolt 4) in the bolt assembly is assembled on the engine upper cover 1, and is used to fix the pull-out force measuring plate 2 on the engine upper cover 1, so that the pull-out force measuring plate 2 is horizontally aligned with the engine upper cover 1, and the second bolt assembly (i.e., the short bolt 9) is vertically assembled at the center position of the pull-out force measuring plate 2, that is, the short bolt 9 is screwed into contact with the pressure sensing unit 200 through the pull-out force measuring plate 2, and pressure is applied to the pressure sensing unit 200. At this time, the pressure sensing unit 200 will generate a pressure signal after receiving the force applied by the short bolt 9. At this time, the force will be evenly transmitted to the ignition through the pull-out force measuring cylinder 6 and the pull-out force measuring disc 7. Coil sealing ring 8, in order to avoid local stress concentration, because the pressure signal will not be directly displayed, so the data acquisition unit 300 is required to convert the pressure signal into pressure data that can be displayed and recorded. As the second bolt assembly is continuously screwed in, the force received by the pressure sensing unit 200 is continuously increasing, which means that the pressure applied to the ignition coil sealing ring 8 is continuously increasing. At this time, the pressure signal is monitored and measured in real time by the pressure sensing unit 200 until the ignition coil sealing ring 8 falls off from the engine upper cover 1. The data acquisition unit 300 collects the pressure signal generated by the pressure sensing unit 200 at this time, and converts the pressure signal into pressure data, and records the pressure data as the pull-off force data of the ignition coil sealing ring 8.

[0056] Furthermore, in order to accurately measure the pull-out force data of the ignition coil sealing ring 8, the embodiment of the present application also needs to monitor the screw-in position and screw-in depth of the bolt in real time, and when the screw-in position or screw-in depth of the second bolt assembly does not meet the preset screw-in conditions, the screw-in position and screw-in depth of the second bolt assembly are adjusted by the adjustment unit. For example, the screw-in position is adjusted by adjustment components such as locating pins or locating plates, the screw-in depth is adjusted by components such as stop rings or depth control devices, or automatically adjusted by a position sensor, without specific limitation here. This avoids position misalignment of the second bolt assembly or abnormal screw-in force, thereby ensuring precise control.

[0057] Optionally, the above-mentioned ignition coil sealing ring pull-out force measurement system 10 further includes: a data analysis unit for comparing and analyzing the pull-out force data of the ignition coil sealing ring with historical data, and obtaining the reason for the ignition coil sealing ring to fall off based on the analysis result.

[0058] Optionally, the data analysis unit also includes: a judgment subunit, used to judge whether the difference between the pull-out force data of the ignition coil sealing ring and the preset design data is within the preset threshold range; if the difference between the pull-out force data of the ignition coil sealing ring and the preset design data is within the preset threshold range, it is judged that the reason for the ignition coil sealing ring to fall off is the aging of the ignition coil sealing ring; otherwise, it is judged that the reason for the ignition coil sealing ring to fall off is the deformation of the engine upper cover.

[0059] Among them, the preset design data and the preset threshold range can be set by technical personnel in this field according to actual measurement requirements, or obtained through a limited number of computer simulations, and are not specifically limited here.

[0060] Specifically, after obtaining the pull-out force data of the ignition coil sealing ring 8, the embodiment of the present application needs to compare and analyze the pull-out force data of the ignition coil sealing ring 8 with historical data, and obtain the reason for the detachment of the ignition coil sealing ring based on the analysis result.

[0061] Specifically, the embodiment of the present application adopts a brand-new ignition coil sealing ring 8 to perform a pull-out force measurement test. After obtaining the pull-out force data obtained by the brand-new ignition coil sealing ring 8, the pull-out force data is compared and analyzed with the preset design data, such as the R&D design value, to determine whether the difference between the pull-out force data of the ignition coil sealing ring 8 and the preset design data is within the preset threshold range, that is, whether the pull-out force data of the ignition coil sealing ring 8 is close to the preset design data. If the difference between the pull-out force data of the ignition coil sealing ring 8 and the preset design data is within the preset threshold range, that is, the ignition coil sealing ring If the pull-off force data of the ignition coil sealing ring 8 is close to the preset design data, it means that the engine upper cover 1 meets the use requirements. At this time, it can be determined that the reason for the falling off of the ignition coil sealing ring 8 is that the ignition coil sealing ring 8 is aging, which causes the skeleton to loosen and eventually fall off; if the difference between the pull-off force data of the ignition coil sealing ring 8 and the preset design data is not within the preset threshold range, that is, the pull-off force data of the ignition coil sealing ring 8 is much smaller than the preset design data, it means that the engine upper cover 1 does not meet the use requirements. At this time, it can be determined that the reason for the falling off of the ignition coil sealing ring 8 is that the engine upper cover 1 is deformed, causing the ignition coil sealing ring 8 to fall off.

[0062] In summary, the ignition coil sealing ring pull-off force measurement system 10 designed in the embodiment of the present application is completely in fit with the sealing ring rubber skeleton and is evenly stressed, so the measured data is more accurate and the sealing ring is not easily damaged. At the same time, the pull-off force measurement is based on the actual engine upper cover to restore the actual working conditions and environment. The measured data is closer to the actual usage scenario, which is helpful for the optimized design and development of the sealing ring rubber skeleton and the definition of more applicable standards, thereby reducing production costs.

[0063] According to the ignition coil seal ring pull-out force measurement system of the embodiment of the present application, a pull-out force measurement component is installed on the engine upper cover; a pressure sensing unit installed on the pull-out force measurement component is used to measure the pressure signal when the ignition coil seal ring falls off; a data acquisition unit is connected to the pressure sensing unit, and is used to convert the pressure signal into pressure data when the ignition coil seal ring falls off, so as to obtain the pull-out force data of the ignition coil seal ring based on the pressure data. Thus, the pull-out force measurement in the related art cannot completely restore the actual working conditions, and effectively monitor the pull-out force difference before and after the aging of the seal ring rubber, thereby reducing the reliability of the verification parts. By using a new ignition coil and a real engine upper cover to measure the pull-out force, the pull-out force difference before and after the aging of the seal ring rubber can be accurately monitored to verify the reliability of the parts.

[0064] Next, a method for measuring the pull-out force of an ignition coil sealing ring according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0066] In step S301, a pressure signal generated by a pressure sensing unit when an ignition coil sealing ring falls off is received;

[0067] In step S302, the pressure signal is converted into pressure data;

[0068] In step S303, the pull-out force data of the ignition coil seal ring is obtained based on the pressure data.

[0069] Optionally, after obtaining the pull-out force data of the ignition coil sealing ring based on the pressure data, the method further includes:

[0070] Determine whether the difference between the pull-out force data of the ignition coil seal ring and the preset design data is within a preset threshold range;

[0071] If the difference between the pull-off force data of the ignition coil seal ring and the preset design data is within the preset threshold range, it is determined that the reason for the ignition coil seal ring to fall off is aging of the ignition coil seal ring; otherwise, it is determined that the reason for the ignition coil seal ring to fall off is deformation of the engine upper cover.

[0072] According to the ignition coil seal ring pull-out force measurement method of the embodiment of the present application, a pull-out force measurement component is installed on the engine upper cover; a pressure sensing unit installed on the pull-out force measurement component is used to measure the pressure signal when the ignition coil seal ring falls off; a data acquisition unit is connected to the pressure sensing unit, and is used to convert the pressure signal into pressure data when the ignition coil seal ring falls off, so as to obtain the pull-out force data of the ignition coil seal ring based on the pressure data. Thus, the pull-out force measurement in the related art cannot completely restore the actual working conditions, and effectively monitor the pull-out force difference before and after the aging of the seal ring rubber, thereby reducing the reliability of the verification parts. By using a new ignition coil and a real engine upper cover to measure the pull-out force, the pull-out force difference before and after the aging of the seal ring rubber can be accurately monitored to verify the reliability of the parts.
